## Overview

This repository is course material for system integration and networking, not a single runtime application. The learner’s path is through the curriculum and topic guides, then into practical example applications. The README documents the three course themes, reference material, and practice apps; sampled code shows Mission Control’s heartbeat-to-status/logbook flow and the monitoring API’s Prometheus endpoint. Other app internals are represented only at the directory level because their source was not sampled.

Main entry points: [`docs/thema-1.md`](https://github.com/jacobmenge/kurs-unterlagen/blob/main/docs/thema-1.md) (Planning & Integration), [`docs/thema-2.md`](https://github.com/jacobmenge/kurs-unterlagen/blob/main/docs/thema-2.md) (Operations Topics), [`docs/index.md`](https://github.com/jacobmenge/kurs-unterlagen/blob/main/docs/index.md) (Course Overview), [`apps/docker-compose-mission-control/backend-node/server.js`](https://github.com/jacobmenge/kurs-unterlagen/blob/main/apps/docker-compose-mission-control/backend-node/server.js) (Mission Control Backend)
